Class: RuboCop::Cop::Bundler::InsecureProtocolSource

Overview

The symbol argument `:gemcutter`, `:rubygems`, and `:rubyforge` are
deprecated. So please change your source to URL string that 'rubygems.org' if possible, or 'rubygems.org' if not.

This autocorrect will replace these symbols with 'rubygems.org'. Because it is secure,
HTTPS request is strongly recommended. And in most use cases HTTPS will be
fine.

However, it don't replace all `sources` of `http://` with `https://`.
For example, when specifying an internal gem server using HTTP on the
intranet, a use case where HTTPS can not be specified was considered.
Consider using HTTP only if you can not use HTTPS.
